CAGE-RING FOR BALL-BEARINGS Specification of Letters Patent.

Application filed August 1, 1911.

Patented Jan. 2,1912, Serial No. 641,732.

To all whom it may concern:

Be it known that I, AUGUST SoHILLINc, subject of the German Emperor,residing at Biclefeld, Germany, have invented new and usefulImprovements in Gage Rings for Ball-Bearings, of which the following isa specification. 1, a

The present invention relates to a onesided cage-ring for ball bearingswith fixed partitions separating the various hollowed out cages. Thecages are arranged as closely together as possible leaving only narrowpartitions between them, so that as large a number of balls as possiblewill find room in the bearing and as great a capacity as possible isgiven to the bearing.

7 The characteristic feature of the present invention consists in thatthese narrow partitions serve to receive a closing elastic ring of thekind as is already known in other types of ball bearing cages. Whereas,however, in the previously known devices movable or pivot-able partswere employed for holding the elastic ring or the cage-ring had to bedeformed for allowing of theelastic ring being fitted, the, said elasticring is according tothe present invention secured in the fixedpartitions of the one-sided and one pieced cage-Ting in a manner, whichwill safeguard the absolute steadiness and accuracy of its position. Thefixing partitions remaining between the individual cages are namelyundercut, and in these undercut recesses the elastic ring will fitexpanding outwardly or inwardly.

In the drawing a cage ring for a ball bearing is shown in twoperspective views of which Figure 1 is a view with the recesses openingradially outward, and Fig. 2 is a view with the recesses openingradially inward. The known two runner rings employed together with itforforming the coniplete bearing have been omitted.

The cage ring consists in both figures of a disk a, in which theindividual cages have any othersuitable method. The partitions 0remaining between the cages are undercutvertically or almost verticallyto the longitudinal extension of the partitions. Into these undercutrecesses c is placed in Fig. 1 an elastic ring (Z expanding inwardly,which ring will unalterably maintain its position to the balls which itprevents from falling out of the cages and consequently out of the ballbearing.

The' balls are placed in known manner first intothe runner rings, thenthe one-sided cage-ring is fitted which will receive the balls,whereupon the cages are closed by the elastic ring being placed intoposition.

The arrangement according to Fig. 2 differs from that according to Fig.1 by that the undercuts extend from inside toward outside and thereforein this case an elastic ring will be employed which expands out: wardly.p t

The combination of the one-sided cagering with hollowed cages and theelastic ring, which can be placed in position without any need of,calking or riveting of parts of the cage-ring is particularlyfavorable-for the assembling and dismantling of the 'ballbearing.

The operation is very quickly and easily carried out and neverthelessthe relative positions of the cage ring, for the balls and the elasticring I claim:

A one sided cage ring for ball bearings comprising'acircular memberhaving a plurality' of ball receiving cavities, and fixed axiallydisposed partitions between said cavities said partitions having theirouter and inner portions respectively of different are absolutelysafeguarded.

elevation, the elevated portions overhanging the depressed portions andforming laterally opening undercut recesses, and an elastic ringinserted in said recesses by distortion from its normalposition.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
